Dadgad Demystified
This is a popular open tuning used globally in many guitar genres, and yields fresh and imaginative alternatives to Standard Tuning. Dadgad is an excellent tuning for fingerstyle, strumming, slide, tapping, and harp-like sequencing of scales, modes, and motifs, and much more. I have a clear system which aids in demystifying this tuning and creating strategies in which to explore its altered fingerboard matrix. To many, Dadgad is the Standard Tuning of Open Tunings.
I have been playing, composing, recording, and teaching in this tuning for more than 20 years. I'd be happy to share this with you. If you are interested in the exploration of Dadgad for composition and improvisation, please contact me.
Peace <^>
__________________________________________________
Part One | Dadgad is a suspended 4th tuning: 1 5 1 4 5 1.
Over the years of self study, beginning with folk & bluegrass, & traversing various hybrids of rock, fusion, & North Indian classical music, I've had the great good fortune to study with five master players & teachers: Ali Akbar Khan in Northern California; Martin Simpson, Ratnakar Vyas, & Isaac Guillory in London; and Hari Har Rao in Los Angeles. I played fingerstyle & slide guitar with these teachers. Dadgad was the tuning of choice.
I like the sound of open strings ringing in combination with fingered strings. Dadgad has some advantages in this department. Standard tuning has 3 keys which use all the open strings: ..C Major ..G Major & ..D Major; 2 keys that use 5 of the open strings: A Major & F Major; and 1 key that uses 4 of the open strings: E Major. Dadgad has 5 keys that use all the open strings:..Bb Major ..F Major ..C Major ..G Major & ..D Major; 1 key that uses 5 of the open strings: A major; and 1 key that uses 4 of the open strings: Eb Major.
The 3 D's in the tuning and 2 A's produce strong harmonic overtones. As Dadgad has 7 adjacent Keys from Eb Major to A major [following the musical curve of the Circle of 5ths] with so many open strings, it therefore becomes an excellent choice for the consideration of [but not limited to] 7 D tonal centers, their modal perspectives, the keys from which they are derived, and the other rotations (modes) of those keys. Consider the D tonal center modes below. All the D modes are rotated except for 1> D Ionian or the D major scale: D E F# G A B C# D. Otherwise with the other modes, there is displayed the key from which the mode is derived, as well as its corresponding rotation.
